.DYIEING-MACI-IINE.

Application filed December 29, 1916.

To (ZZZ whom it may concern:

Be it known that I, I-lowano M. DUDLEY, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Dyeing-lilachines, of which the following is a specification.

My invention relates to a dyeing machine and refers particularly to a machine adapted for the dyeing of textile fibers compressed within a dyeing chamber, the dyeing being accomplished by the forced passage of the dye liquor through the fiber mass.

Among the objects of my invention is a dyeing machine particularly suitable for the dyeing of warps in the ball, whereby the condition of the fiber may be accurately and readily judged at any stage of the treatment without opening the dyeing chamber and whereby even results may be obtained without disturbing the fiber to be dyed.

Other objects of my invention. will be evident upon a coi'isideration of my specifications and claims.

l have found that the even or uneven dyeing results obtained in a machine of this general character depends largely upon the particular shape of the openings through which the dye liquor enters the fiber mass, and that unevenness can be prevented by the use of openings of a particular shape, the conformation of which enables the liquor to spread itself through the fiber mass without the formation of channels of flow.

l have further found that this desirable result can be obtained it such openings are of an elongated form, diverging upwardly into the dyeing chamber or of a double diverging conformation, diverging both upwardly into the dyeing chamber and downwardly into the source of dye liquor.

Related forms of my device are shown in the accompanying drawings, in which similar parts are designated by similar numerals.

Figure l is a side View of one form of my invention, partly broken away to disclose a portion in cross-section.

Fig. 2 is a cross-section through the line 2-2 of Fig. 1.

introduced into the lower portion of the liquor supply chamber.

Fig. 5 is a broken cross-section of a modification 0f the liquor supply chamber showing the plates extending from the bottom to the top thereof.

Fig. 6 is a cross-section of the pump chamber showing the plates extending downwardly therein.

Fig. 7 is a cross-section of a modification of the foraminous plate.

Fig. 8 is a top view of Fig. 7.

Fig. 9 is a cross-section. of a. modification of the foraminous plate.

Fig. 10 is a top View of Fig. 9.

The outer portion of the dyeing machine comprises the cylindrical shell 7 and the cylindrical shell 8, fixedly attached to each other by the bolts 9, 9; the conical shaped bell 1O fixedly attached to the shell 8 by the bolts 11, 11 and the centrifugal pump 12 fixedly attached to the shell 10 by the bolts l3, 13. A toraminous plate 14 is situated between the shells 7 and 8 and is integral with the wall of the chamber 8. The forainiuous plate l i is of a grate construction. The bars l6, l6 taper upwardly and down wardly from their center lines, forming diverged openings between them for the pas sage of liquor.

The machine is provided with a removable annular formanious plate 17, the construction of which is similar to the foraminous plate 141-.

An annular angle-shaped member 18, is slidable within the shell 7, capable of abutment upon the plate 17 and maintained in any desired position by means of the thumbscrews 19, 19, which thread within the shoulders 20, 20 fixedly attached to the shell 7.

A series of plates 21, 21 are positioned in the upper interior portion of the shell 10, the plates extending across the chamber formed by the shell, their upper and lower ends being tapered.

A series of plates 22, 22 are positioned in the lower interior portion of the shell 10, the plates extending across the chamber in the same plane as the plates 21, 21, their upper and lower ends being tapered.

In the modification shown in Fig. 5, the plates 21 and 22 are replaced by plates 23, 23, extending from the top to the bottom of the chambers Within the shell 10.

In the modification shown in Fig. 6, the plates 22, 2 2 are replaced. by plates 2d, 24: which extend downwardly beyond the lower portion of the chambers within the shell 10 into the chamber of the rotary pump In the modification shown in Figs. and 8, the ioraminous plates let and 1'? are formed of square bars 41, 41, so situated that the openings 1-2, 4-2 between the bars 41,41, diverge upwardly and downwardly,

In the modification. shown in Figs. 9 and 10, the toraminous plates 1 1- and 1'? are formed of round bars i3, 43, to allow oil: the divergent openings n, 44.

A. perforated steam pipe 25 is introduced into the chamber formed by the shell In order to facilitate reference to the various chambers, they will hereafter be referred to as the top chamber 96, the dyeing chamber 27, the liquor supply chamber 28., the plate chamber 29, and the pump chamber 30.

An oventiow pipe 31 connects the top chamber 2-6 with the centrifugal pump 12 to allow of continuous flow of the liquor upwardly through the machine.

A pipe connects the pump 12, with a liquor supply tank, not shown, the pipe 32 carryingthe valve A pipe 3-1, 35 extends from within the liquor supply chamber to a point above the top chamber 26, and carries a then mometer 36 for determining the temperature passing through the pipe 3st, 35.

A sample dyeing machine 37, exactly similar to the above described dyeing machine, except in smaller proportions, is connected to the liquor supply chamber 28 by the pipe 38 and to the top chamber 26 by the pipe 39, The sample material in the machine 3'? is examined by removing the top 40 which is threaded to the sample machine 37.

The operation ot the device is as follows:

The annular member 18 and the l oramb nous plate 17 are removed, the goods to be tre ted introd ced into the dyeing chamber 27, the plate 17 replaced and pressed down upon the goods by means of the member 18. A. small quantity of the same goods is placed in the sample device 37. The pump 12 is started and the valve 33 opened, allowing the liquor to how through the pipe 32 into the pump 12, by which it is forced upwardly through the pump chamber 30, the plate chamber 29, the liquor supply chamber 28, and the goods in the dyeing chamber- 27, into the top member 26. 'l l hen the liquor has reached a height to allow its flow through the pipe 31 back into the pump 19 the valve 33 is closed and the liquor is forced continuously through the device as above stated.

'Fron time to time, the pump 12 isotop pod, the top all is removed for the purpose 1,258,55tt4l of examining the condition oil? the dyeing operatital, and is then replaced, the pump 12 started and the dyeing continued until it has reached a satisftactory condition.

lit is evident that during: this operation the liquor is forced upwardly through the plates 22, the upper edges of which cause it to spread out upon leaving the space between the plates, the same result being; obtained as the liquor leaves the spaces between the plates 21, 521. As the liquor leaves the spaces in the toraminous plate 16, the diverp. nt edges oi the separating members, causes it to spread out and to impinge upon the material in the dyeing chamber 27" in a practically ui'iitorm manner, and that the continuing of thi flow will force the liquor throughout the mass of goods, and will prevent the formation oi? channels through the goods. as the plate 17 is the same as plate 16, the pressure will be maintained in the dyeing chamber 2?, and the liquor will be compelled to penetrate the goods inward y toward each of th openings in order to escape.
